The Lowdown
Alright folks, Rusty here. Let’s get into it for Kennebunk Beach.
Straight up, I’ve got to be honest with you – this 16-day window looks pretty grim. We’ve got a long stretch of small, weak waves and onshore junk. The water is sitting at 65°, which is a touch warmer than usual for this time of year, but that’s the only bright spot. There’s just no real energy to get excited about. The combined swell energy is mostly in the low double digits, barely reaching 114 for a single session, and that’s weak. We’re looking at a wave height that barely cracks 3ft, and that’s with a short, weak period.
The first real recommendation we get is for Sunday morning, September 6th. There’s a 3ft swell from the ENE, but the period is a paltry 6 seconds, so it’s just small, crumbly shorebreak. The wind is a cross-off from the north, which will keep it clean, but even then, the energy is only 114. It’s not going to be worth paddling out for. This is a sheltered spot, so it doesn’t grab much of anything.
The pattern continues with nothing but “poor surf conditions” for the entire forecast. Every slot is a zero out of ten. There’s a little bump of energy (97) on the afternoon of Sunday, September 13th, with a 3ft swell from the SE and a 8-second period, but the wind is straight onshore from the SSW. That’s a mess.
Looking further out, the tail end of the period on the 19th of September has a glassy afternoon with a 0.7ft swell from the ESE and a long 11-second period, but the energy is only 21. It’s flat. The 17th of September morning has a 0.7ft swell from the ESE with a 13-second period and a clean offshore wind from the ENE, but again, it’s just not enough water to push.
There is no standout. Nothing is even close. It’s a full 16-day stretch of donuts. For a spot like this, it’s one of those runs where the forecast can change, but right now, it’s a total blank. If you’re desperate for a paddle, the morning of the 6th is your best bet just for the clean conditions, but don’t expect a wave. Honestly, with the wind patterns and the small, weak swell, this setup looks more interesting for kite surfing than paddle surfing.
Rusty.
